Modify property of object in List [Answered]

I have a struct like this:

public struct MyStruct
{
    public ulong Id { get; set; }

    public string MyProperty { get; set; }
}

public struct MyStruct
{
    public ulong Id { get; set; }

    public string MyProperty { get; set; }
}

And I have a

List<MyStruct>

List<MyStruct>

. I want to modify

MyProperty

MyProperty

for a certain

MyStruct

MyStruct

in the list, using the

Id

Id

property. I tried this:

MyList.Where(x => x.Id == id).ToList().ForEach(x => x.MyProperty = myVariable);

MyList.Where(x => x.Id == id).ToList().ForEach(x => x.MyProperty = myVariable);

But it didn't work.
